Non-Negativity is a Quantum Phenomenon
1--7 March 2009

In recent publications, the same combinatorial description has arisen for three separate objects of interest: non-negative cells in the real grassmannian (Postnikov, Williams); torus orbits of symplectic leaves in the classical grassmannian (Brown, Goodearl and Yakimov); and, torus invariant prime ideals in the quantum grassmannian (Launois, Lenagan and Rigal). The aim of this meeting is to explore the reasons for this coincidence in the grassmannian in particular, and to explore similar ideas in more general settings.
